IONICON Analytik introduces a new compact high-resolution instrument. For the first time IONICON combines high sensitivity with a high mass resolving power in a small and lightweight PTR-TOFMS. 


The PTR-TOF 4000 has already been successfully deployed aboard NASA flying laboratories for air quality monitoring. 


The development

 

In 2014 the PTR-TOF 1000 was launched. A new platform developed by IONICON with the aim to create a compact and affordable PTR-TOFMS allowing customers from all over the world in various application areas to benefit from the company’s advanced time-of-flight technology. 


Inspired by this achievement and rewarded with immediate success in the market of more than 30 PTR-TOF 1000 systems sold since its introduction, the IONICON took this concept one step further. 


The new instrument 


“We decided to develop the ’no-compromise’ trace VOC analyzer. A high-resolution PTR-TOFMS but small, lightweight, extremely sensitive and also competitively priced”, IONICON CEO Lukas MÄRK explains the challenges. 


These efforts lead to the new PTR-TOF 4000 featuring the new Hexapole “ION-GUIDE” technology and a novel high-resolution TOF. The results are an impressing mass resolution of up to 4000 m/Δm and a sensitivity of 200 cps/ppbv with a low detection limit of below 5 pptv. 


The PTR-TOF 4000 complements IONICON’s PTR-TOFMS series ideally, being positioned in between the PTR-TOF 1000 system and the company’s current flagship instrument, the PTR-QiTOF. 


Proven aboard NASA’s flying laboratories 


Prototypes of the new PTR-TOF 4000 have been extensively tested in the field. A long-standing cooperation between the University of Innsbruck and IONICON made it possible to participate in airborne campaigns aboard NASA’s atmospheric research aircrafts for measuring air pollution in the atmosphere (e.g. KORUS-AQ). Mr. Märk comments on this mutually beneficial collaboration: „We were able to test the PTR-TOF 4000 prototypes under the most demanding conditions and could also benefit from the scientists’ experience when optimizing the performance of our novel trace VOC analyzers.“
